MAP-HANGING uEvles.

SPECIFICATION formingpart of Letters Patent No. 747,829, dated December-22, 1903. Y

Application filed March 2, 1903. Serial No. 145,633. (No model.)

To all int ham, it may concern:

Be iii-known that I, FRED .ZIMMERMAlN, a

citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvementin M'ap-Hangi-ngDevices, (Case No. 1,) of which the following is a full, clear,

, preferably of wood, and is provided with holes therethrough spaced to register with the boltsprojecjting from the baseportion. The maps or other display-sheets are clamped between saidbase portion and the cap portion by means of thumb-screws which engage the threaded ends of the bolts.

One feature of my improved device lies in means for cutting perforationsin the maps as they are applied to the bolts. To this end I provide the holes in the cap portion with thin steel bushings,which at their inner ends are beveled to a sharp cutting edge, the cap.-

strip being held against the topof .the map. about to be hung, so that the bushings register with the ends of the bolts. Byaslight push the sharp edges of the bushings, in conjunction with the ends. of .the bolts, perforate ;.the map, which, together with the strip,a're

received by the bolts. The thumb-screws. are now applied to the .bolts and the map or. map's securely clamped between the base and --th'e c'ap.. Each successive map maybe hung I a trifle higher than the preceding map and may beprovided withrings at its lower edge. To display any ;,one of 'the.maps thus suspended, an ordinary cord-catch curtain-pul- .ley maybejscrewed into the ceiling or into a "projection extending from the device or from v the wall, and by means of acord passing through said pulley and having at its one end a hook the ring on themap just in front of thethe base 1.

by referring to the accompanyingdrawings,

in which- Figurel is a side view of the: device, showing the manner of displayinga desired map. Fig.2 is a front view showing the same as Fig. 1. Fig. 3 is a top view showing a map in the act of being applied to the bolts. Fig. 4. is a view of the pulley employed.

Like characters of reference refer to like parts throughout the figures.

A base-strip 1, which may be screwed or otherwise fastened to a wall, has extending forwardly therethrough a series of bolts 2 2, which bolts are preferably of steel and threaded at their ends. A cap-strip?) is provided with a series of holes 4: 4., spaced to register with the screws 2 2. These holes are provided with thin bushings 5 5, preferably of steel, and extending slightly beyond the inner edges 6. 6 of the holes 4 4, these extended ends being beveled to a sharp cutting edge. The bushings also protect holes 4 4 against wear.

In Fig. 3 is shown the manner of applying a map 7 to the hanger. The cap-strip is held against the map,-.near theitop edge thereof, the mapand cap inv this relation being held so that thebushing-openings register with the ends of the bolts. By pushing, against the strip circular perforations are cut through the map by the. sharp. edges of the bushings,

whereupon the map and the strip are received by the bolts.- ,The'perforations are thus clear cut and have unbroken edges, enabling the maps to hang from the bolts without danger of the material thereof beginningto rupture at their perforations. The thumb-screws 8 8 are now. applied to the threaded ends of the bolts and screwed down to, clamp the maps between the strip and the base. To prevent the bolts from turning as the thumb-screws are applied, the heads 9 9 thereoflare'rectangular and countersunk into the material of The maps are preferably hung so that each map is a trifle higher than its predecessor and may be provided at its lower edge with stiffening-strips 10 l0,provided with rings 11 11.

To display a certain map, I preferably provide means whereby all the maps in front of such desired map are raisedout of the way. This may conveniently be accomplished by the use of a cord-catch curtain-pulley 12,which may be screwed into the ceiling or into any other support. A cord 13, passing through such pulley is provided at its end with a hook 14, which book engages the ring on the map directly in front of the map to be exhibited. By pulling the cord the maps hanging before the desired map are raised out of the way, and by pulling said cord toward either side it is caught by the pulley, and the raised maps are held in place.

The map-hanger may be made of any size and strength for the accommodation of any number of maps. Changes may also readily be made in the structure thereof without departing from the spirit of the invention, and

I therefore claim as new and desire to secure by Letters Patent- 1. In a device of the class described, the combination of a base-strip, a plurality of bolts extending forwardly from said basestrip for receiving maps to be suspended therefrom, a cap-strip adapted to be received by said bolts, and means associated with said cap-strip for cutting regular perforations through said maps.

2.
